Boom Boom boom boom crane lifting cranes, also known as crank, a new structure, flexion freely, flexible operation, energy efficient features. Rail crane operation, pushed the button will load was lifted, the use of beam bending and rotational movements standard crane, avoid objects in the work area within the control to maximize the working area. Gently push and pull, we can achieve a position of any of the work area. Boom crane for machinery manufacturing, railway, chemical industry, light industry, production or maintenance of occasions, particularly in dense device, a short distance lifting, for frequent application of the product line will enhance production efficiency. From the weight of 125KG to 500KG. Cantilever crane arm, also known as the arms hanging, double jib crane mounted slip ring slip ring assembly jib cranes should Hold the electrical slip ring, mounted on the spindle cantilever beam crane main beam of the upper portion of the column through a side door aperture . There slip ring bore a keyway, using electrical slip ring keyway aligned to key pin rectangular beam on the spindle keyway installation, and then install the insulating gaskets and tighten the locking cap over the line. Finally, adjust the position of the brush holder, you know the appropriate date. Jib cranes Cranes for light intensity, cranes by the column, the pivot arm and hoist rotary drive unit composed of the lower end of the column is anchored by a concrete foundation, driven by a boom swing cycloid, electric hoist boom I-beam for about a straight line running and lifting heavy objects. Crane jib hollow steel structure, light weight, span, lifting large crane boom, economical and durable. Built-in running gear, made of special plastic with rolling bearings go round crane, small friction, brisk walking; small structure size, especially help to improve the hook travel. When 0.5t-2t crane jib crane beam installation 0.5t-2t jib crane beam installation, rotary spindle aligning bearing hole at the top of the column; roller against the upright circular orbit slow down. Force through a side door pillar holes retaining washer and a round nut. Installation slip ring contacts mounting method has been talked about the last article, I am not doing explained.
